GAS-VALVE.

Specification of Letters Patent.

f Patented Apr. 1, 1913.

Original application led July 15, 1909, SerialhNo. 507,725. Divided and this application led June 1,

Serial No. 5 64,446.

To all whom t may concern Be it known that I, JAMEs A. HERRIGK, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Gas- Valves, of which the following is a specification.

This invention relates to producer gas apparatus and is a division of my application filed July 15th, 1909, Serial No. 507,725, for gas producer apparatus.

One of the objects of the invention 1s to provide new and improved valve mechamsm adapted to be used for gas producing and gas consuming apparatus.

Another object is to provide improved means whereby t-he valve mechanism may be kept cool and thereby prevented from becoming burned out.

Another vobject is to provide a valve construction such that the furnace is at all times in direct communication with the stack.

Other objects will be in part obvious, and in part specifically referred to.

The invention accordingly consists in the features of construction, combinations of elements and arrangements of parts, which will be exemplified in the construction hereinafter described, and the scope of the application of which will be indicated in the appended claims. In the accompanying drawings wherein is illustrated two preferred forms of embodiments of my invention; Figure 1 is a view in vertical section of a preferred embodiment of the same; Fig. 2 is a horizontal sectional view looking downward; Fig. 3 is a view taken substantially on the line 3 3 of Fig. 2; Fig. 4 is a view in vertical section of another embodiment of my invention; and Fig. 5 is a view partly in vertical section and partly in elevation of the embodiment shown in Fig. 4.

Similar reference characters refer to similar parts throughout the several iigures of the drawings.

Referring now to the drawings and particularly to the embodiment illustrated in Figs. 1 to 3 inclusive 1 and 2 respectively indicate conduits which may extend from a gas producer or any suitable source of gas supply. These conduits lead into compartments 3 and 4 provided respectively with passage ways 5 and 6 which lead into conduits 7 and 8 each of which is adapted to be connected with a gas utilizing apparatus such as a furnace. Passage ways 5 and 6 are adapted to be closed as by means of valves 10 and 11 mounted to swing upon supports 12 and 13 as shown. 14 denotes a valve chamber which is connected with the conduits 7 and 8 as by means of passage ways 15 and 16, said passage ways being adapted to be closed -by means of swinging valves 17 and 18 mounted upon supports 20 and 21. These valves may be connected to move in unison and in alternation, so that when one passage way is closed the other is open; valves 10 and 11 being adapted to be similarly connected. Valves of each pair comprising those designated at 11 and 17, and 12 and 18, may be connected to a single operating rod and actuated by a single lever. The bottom wall of chamber 14 is provided with channels as at 22 adapted for containing water which keeps the various parts cool and into which dip the flanges 23 of the valve. The valve may be cooled if desired by means of water pipes 24 which may be provided with a plurality of small apertures through which water may be distributed upon the bed. Valve chamber 14 connects with the stack 25 as by means of the passage way 26. lllhen the parts are in the position shown-in the drawings gas is discharged through conduit 2 into compartment 4 whence it passes through passage way 6 which leads to the furnace or other `gas utilizing apparatus, and the products of combustion return through conduit 7 and' into valve chamber 14 through conduit 26 and is then discharged into the stack through the passage way 25. When the valves 11, 12 and 17, 18 occupy their opposite directions, the direction o-f the flow of gas and of the products is in the opposite direction through the apparatus; the products of combustion entering the valve chamber 14 through the passage way 15 to be discharged into the stack through the passage way 25.

The embodiment of my invention sho-wn in Figs. 4 and 5 differs from the one above described in that the stack 27 is taken ofl:1 from the rear port-ion of the valve chamber 14 and instead of having independent valves for the passage ways 15 and 16, a unitary structure is provided as at 28 comprising two valve members 30 and 31, mounted upon the support 32 carried by the upright 33, said support being located immediately above a water bath provided in the channel 34 whereby the parts are cooled. The operation of this embodiment of my invention is similar to that just described, it being understood that when the valve ll is open and valve l0 closed, the gas will enter through conduit 2 and be discharged from the furnace through conduit T into valve chamber 14 and out of the stack 2T; valve member 3l preventing the passing of the products of combustion into the conduit S, and valve member 30, allowing the products of combustion to flow through the passage `way 15. W hen the valves are reversed the flow of gas and escaping products of combustion are in the opposite direction to the entire apparatus.

Accordingly it will be seen that have provided an apparatus particularly well adapted to attain, among others, all the ends and objects above enumerated in a simple yet efficient manner.

It will be observed that by means of the above described construction, the stack is at all times in direct communication with the furnace, and any tendency toward explosion or kick backs when the valves are reversed is entirely eliminated.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, itis intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention, which as a matter of language, might be said to fall therebetween.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

l. In an apparatus of the class described, the combination of a structure having a generally flat top comprising a horizontally disposed stack flue having an opening in its top, and conduits on opposite sides of the stack fiue, there being two openings in t-he top of each conduit, a water seal base resting upon the flat top of said structure and being flanged in registry with the several openings aforesaid, a separate valve box for the end opening of each of said conduits, said valve boxes resting in and being sealed by the water seal, each of said valve boxes being provided with a swinging valve adapted to close said opening and to be sealed by said water seal, and a third valve boX supported in the water seal and covering the two inner openings of said conduits, there being means provided for opening or closing either one of said openings, said valve means being sealed by said water seal,
